Their incidence varies among different populations and they constitute an anthropo- logical marker. Precise mechanism of formation is unknown and being under the control of genetic background and environmental factors. The aim of the current study is to investigate the incidence of WBs presence, number and topographical distribution according to gender and side in Greek adult dry skulls. Materials and methods: All sutures and fontanelles of 166 Greek adult dry skulls were examined for the presence, topography and number of WBs. One hundred and nineteen intact and 47 horizontally craniotomised skulls were examined for WBs presence on either side of the cranium, both exocranially and intracranially. Results: One hundred and twenty-four (74.7%) skulls had WBs.

  • A 3D Stereotactic Atlas of the Adult Human Skull Base Wieslaw L
    Nowinski and Thaung Brain Inf. (2018) 5:1 https://doi.org/10.1186/s40708-018-0082-1 Brain Informatics ORIGINAL RESEARCH Open Access A 3D stereotactic atlas of the adult human skull base Wieslaw L. Nowinski1,2* and Thant S. L. Thaung3 Abstract Background: The skull base region is anatomically complex and poses surgical challenges. Although many textbooks describe this region illustrated well with drawings, scans and photographs, a complete, 3D, electronic, interactive, real- istic, fully segmented and labeled, and stereotactic atlas of the skull base has not yet been built. Our goal is to create a 3D electronic atlas of the adult human skull base along with interactive tools for structure manipulation, exploration, and quantifcation. Methods: Multiple in vivo 3/7 T MRI and high-resolution CT scans of the same normal, male head specimen have been acquired. From the scans, by employing dedicated tools and modeling techniques, 3D digital virtual models of the skull, brain, cranial nerves, intra- and extracranial vasculature have earlier been constructed. Integrating these models and developing a browser with dedicated interaction, the skull base atlas has been built. Results: This is the frst, to our best knowledge, truly 3D atlas of the adult human skull base that has been created, which includes a fully parcellated and labeled brain, skull, cranial nerves, and intra- and extracranial vasculature. Conclusion: This atlas is a useful aid in understanding and teaching spatial relationships of the skull base anatomy, a helpful tool to generate teaching materials, and a component of any skull base surgical simulator. Keywords: Skull base, Electronic atlas, Digital models, Skull, Brain, Stereotactic atlas 1 Introduction carotid arteries, among others.

    Review Article International Ayurvedic Medical Journal ISSN:2320 5091 TO ELABORATE CONCEPT OF SEVANI WITH THE HELP OF MODERN ANATOMY Dr. Budruk Pramod Appasaheb M.D. Sharir Rachna, L.L.B.(spl), Principal- Hon.Shri. Annasaheb Dange Ayurved Medical College, Ashta. Tal- Walwa, Dist- Sangli, Maharashtra, India ABSTRACT Ayurveda gives new Idea about human being in case of Anatomy, Physiology & other subjects also. Ayurvedokth Rachana Sharir describes about various terminology. In fifth chapter of Sharirsthan Susrut described various parts of the body. Not only various parts of the body, but also number of these parts or organs, is nicely given in this Sharir sankhya vyakarana sharir Ad- hayaya. Anaga, Pratnyaga, Twacha, Kala, Sira, Snayu, Dhamani are described with its numbers & distribution of them. Sivani is the one of structure present in the body. There is Sapta-Sevani present in the body. Structure of Sevani & also importance of it is given by Ayurveda. Though Sevani is mentioned in one sloka, but it has very much important.Its importance is given by comparative study with modern Science. Division of the skull is done by these sevani, as given in modern science. Sevani word gives two references. First is a sapt Shivayna available for the sevani & second in case of sandhi sharir. There is confusion regarding various terms as sevani or simant. With the help of this article I am trying to clarify these concepts with the help of mod- ern science. Keywords: Sevani, Septasevani, Sivani, Tunnasevani,Sutures INTRODUCTION We know that structural & functional science, these structures we can easily corre- unit of the body is cell.
